Output feedback stabilization of nonlinear systems with delays in the input

It is proposed a novel and simple design scheme of output feedback controller for a class of nonlinear systems with delays in the input. By constructing appropriate Lyapunov-Krasovskii functionals (LKF) and solving linear matrix inequality (LMI), the delay-dependent controller making the closed-loop system globally asymptotically stable (GAS) is explicitly constructed. A simulation example is given to show the effectiveness of the proposed design procedure.
